and Brunswick to Hanover. Six weeks later, on 15 October 1847, the opening of the Hanover–Minden line and the Hamm–Minden line created a continuous link to Deutz on the banks of the Rhine opposite Cologne, which was linked to the Western European railway network via the Rhenish Railway’s line to Aachen. With the opening of a connecting line between the Wrocław stations on 3 February 1848 it was connected to the Upper Silesian Railway (completed on 18 October 1847) and the Kraków–Upper Silesian railway (completed on 13 October 1847), creating a continuous rail link from Deutz to Kraków. Less than a year later on 1 September 1848, the William's Railway (Wilhelmsbahn'') was opened from Koźle (Cosel) to Bohumín (now in the Czech Republic, then in the Austrian Empire), closing the gap between the Upper Silesian Railway and the Austrian Northern Railway, which had opened to Bohumín on 1 April 1847. This created a continuous rail link between Berlin and Vienna. On 15 May 1875, a 93 km double-track line was opened as a shorter route between Jasień (Gassen) and Legnica (Liegnitz) via Żagań (Sagan). Takeover by Prussia The Prussian government had acquired shares worth 1.5 million thalers in the NME when it was established, with the right to take it over under certain circumstances. Because the railway's earnings in 1848/49 fell short of expectations, this clause came into effect and at the instigation of the Prussian Minister of Commerce and Industry, August von der Heydt on 1 January 1850 the government took over the management of the company. Although results improved quickly, 18 months later the company's directors offered to sell the railway the state. The Minister of Commerce advocated the purchase, but there was considerable opposition from the Minister of Finance, Carl von Bodelschwingh, who pointed out the railway's significant debt. Ultimately, King Frederick William IV backed the Minister of Commerce on the grounds of the particular economic and military significance of the railway. Despite further protests the purchase was approved and completed on 1 January 1852. The NME thus became a part of the Prussian state railways and the newly created Royal Directorate of the Lower Silesian-Mark railway based in Berlin. The beginnings of industrialisation increased traffic, especially in and around Berlin. In the period up to the 1890s many additional stations were built along the route along with the gradually laying of a second pair of tracks
